Abstract (en)
[origin: WO2011131892A1] The invention relates to a method which includes, for at least two predetermined operating phases of the engine during at least one mission of the aircraft: obtaining measurements of an oil level of the tank, each measurement being associated with an oil temperature and an operating speed of the engine; selecting measurements that represent variations in the oil level, associated with oil temperatures near a reference temperature and with engine operating speeds that are near a reference operating speed; aggregating (F40) the measurements selected during the operating phases and during said at least one mission of the aircraft; and comparing (F60) the aggregated measurements with reference data in order to identify (F70) abnormal oil consumption of the engine.
